MADISON -- Last July, Kevin Nicholson told conservative radio host Mark Belling that he voted for Donald Trump in Wisconsin's 2016 president primary, explaining that he was certain "[Trump] was the only one that had a chance to win a national election."

But in November 2015, another Republican presidential candidate owned Nicholson's heart -- or at least his wallet.

​That month, Nicholson donated $250 to Marco Rubio's presidential campaign, a significant indicator of support that Nicholson never replicated with respect to Trump.

So... when did Kevin Nicholson all of a sudden decide that he was no longer supporting Marco Rubio and become Wisconsin's biggest Donald Trump booster?

Nicholson, who's compared Trump to Abraham Lincoln, won't say. And that isn't the only political transformation question that Kevin Nicholson has yet to definitively answer.
